50 PCS 9.8 x 13.7 Inch 4.5 mil Thick (Single-sided) mylar bags for food storage, Heat Sealable Bags Storage Bags for Food, Coffee Beans, tea, grains, etc. Smell Proof Bags

These mylar bags are a good size. I had ordered a variety-size package initially and found that this 1-gallon size was the most used. They are great for long-term food storage. If you have never purchased from warehouse-type grocery stores because you fear the food item will get spoiled by the time you get around to eating it, this is a solution. Using storage bags allows you to break down the larger boxes and bags of items into smaller sizes to prep them for longer storage time by removing air and sunlight. This extends the viability of foods and with prices going up, now is the time to look for alternatives to the grocery store. I used to use the name-brand plastic vacuum seal bags but found them to frequently become "unvacuumed", which meant that there was an air leak and water, moisture, bugs, etc could come in and ruin the food. These mylar bags have not only a ziplock seal but can be heat sealed. I would suggest using an oxygen absorber pack inside prior to sealing as well as vacuuming out any excess air. If you do not have a vacuum sealer, use the "straw method" to reduce the amount of air in the package before sealing. Straw method - put items in the bag, insert a straw on one edge poking out, zip close the bag all the way up to the straw, suck the air out of the bag using the straw, pull the straw out quickly and seal it tightly.

I have used mylar for a number of years and will not purchase below 4.75 and these do not come close to being that thickness. I will not use for long term food storage. I will use them for other uses. I even hesitate to heat seal with my sealer, I may try using a hand held hair straightener and find one will a low setting.

Este producto es una bendición ya que puedo almacenar diferentes alimentos por hasta 10 años. Avena, almendras, leche, cereales, café. Solo hay que introducir 1 sobre de oxígeno absorbente sellar con una plancha para el cabello y listo.

They are very thin and not as thick as the previous ones I purchased so I returned them

These are what they look like: mylar storage bags. I seal them with a hair straightener, which works great for that purpose. NOTE that I was NOT be able to use them with a food vacuum sealer because there's no air ducts pressed on the inner surface to allow air flow. It was an interesting test, but they seem to be incompatible with food vacuum sealers. They weren't advertised for that, so I'm not removing a star for it. Instead, I vacuum seal food into a gallon size clear bag, then seal the vacuumed clear bag inside this mylar bag for extra protection from UV, air, etc. Has worked great for stuff that is too small to fit inside those giant 5 gallon bags.
